Re: [Boost-users] [Boost Users] Serialization: problems when splittingserialize into load / save

8 Nov 2007


      Hello and thx
I guess that means I cannot change class state in my save method.
That is what I need ! Is there any way around it ?

regards, Oliver

Hello Oliver,
Your save method has to be const.
Regards
Oliver

Betreff: [Boost-users] [Boost Users] Serialization: problems when
splittingserialize into load / save
Hello out there !
I have an urgent problem concerning boost::serialize.
I have split the serialize operation into save / load as described
in the tutorial:
===================================================
   template<class Archive>
           void save( Archive &ar, unsigned int version) {
               m_offlineMode = true;
               // we cannot load more when offline --> always cachedAll
               bool oldCachedAll = m_CachedAll;
               m_CachedAll   = true;
               ar & m_CachedAll;
               ar & m_offlineMode;
               // do not serialize the lock -- use the default
constructor.
               // we assume that no iterators that lock the cache do exist
when serializing.
               // ar & m_Lock;
               ar & m_LookupId;
               ar & m_LookupName;
               ar & m_SequenceNumber;
               //reset old state for the case we want to continue working
               m_CachedAll = oldCachedAll;
               m_offlineMode = false;
           }
template<class Archive>
           void load( Archive &ar, unsigned int version) {
ar & m_CachedAll;
               ar & m_offlineMode;
               // do not serialize the lock -- use the default
constructor.
               // we assume that no iterators that lock the cache do exist
when serializing.
               // ar & m_Lock;
               ar & m_LookupId;
               ar & m_LookupName;
               ar & m_SequenceNumber;
               //reset old state for the case we want to continue working
           }
           BOOST_SERIALIZATION_SPLIT_MEMBER()
===============================================================
The class I serialize is part of a deep class hierarchy that I want to
serialize as a whole.
With the standard serialize() it seems to work, but now the compiler
complains
( when I
want to perform the actual serialization):
error C2662: 'void
jedox::palo::AbstractCache::save<Archive>(Archive &,unsigned
int)' :
cannot convert 'this' pointer from 'const
jedox::palo::AbstractCache' to
'jedox::palo::AbstractCache &'
AbstractCache is the class containing the above load / save operations
kind regards,
Oliver
